IMPROVEMENT IN. LAMP-BURNERS.

Specification forming part of Letters Patent No. 87,601, dated March 9,1869. v

To all whom it may concern:

Be it known that I, ALEXIs THIRAULT, of Brooklyn, in the county of Kingsand State of New York,have invented anew and Improved LampBurner; and Ido hereby declare that the following is afull, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference being had to theaccompanyin g drawings,forming part of this specification, in Which- Figure l is a verticalcentral section of the burner complete; Fig. 2, a similar section of thelower part of the burner with the wicktube detached, the plane ofsection being at right angles to that of Fig. 1; Fig. 3, a similarsection of the upper part or gallery detached Fig. 4, a plan or top viewof the parts represented in Fig. 2.

Similar letters of reference indicate like parts.

My lamp-burner is particularly adapted to burning coal and similar oilswithout smoke or smell, and for giving easy access to the wicktube andwick.

I make use of an air-distributer formed of fine openings for theadmission of air, a chimney-holder for receiving the glass chimney, anda slide for setting around the wick-tube and sustaining the movableportion of the burner upon the wick-tube or parts connected therewith.In the drawings, the wick-tube A passes through the ratchet-cap B, thatmay be formed at its upper surface with a cup-shaped receptacle for anyoverflow from the wick. The body portion f of the burner extends abovethe screw that connects with the reservoir, and

may beformed with perforations, as shown. It

aids in supporting the movable portion or gallery of the lamp. Theperforated plate or wiregauze at a surrounds the lower parts of thewick-tube, and extends to the screw portion of the body. a

The movable portion of the lamp is formed of a chimney-holder, g, fortheglass chimney,

a deflector or cone, 0, with a slot for the flame, a perforatedair-distributer, and a slide setting around the wick-tube.

In order to thoroughly distribute the air and prevent sudden currents ofair aflecting the steadiness of the flame, I have employed theforaminous diaphragms b d e, theperforated portions 11 and 61 beingunited, and this portion forms a base to the burner that rests upon thefixed portion fot the burner when the parts are together, and when theupper portion or gallery of the burner is removed the same, to getherwith the chimney, will stand upright upon said base.

The slide 0 is represented as made of wiregauze, so as to allow any oilthat may run down the outside part of the wick-tube to evaporate andpass with the air to the flame. When the upper part of the burner isremoved the slide 0 will tend to keep the wick-tube clean by re movingany carbonaceous accumulation, and access is thus afforded to thewick-tube and. wick for trimming or other purposes.

What I claim, and desire to secure by Letters Patent, is

l. Theremovable portion of the lamp formed of a chimney-holder, adeflector or cone, and an air-distributer, in combination with a slideor support surrounding the wick-tube, substantially as set forth.

2. A chimney-holder, cone or deflector, and an air-distributer removablefrom the fixed portion of the burner, in combination with a supportaround the ratchet-cap upon which the removable portion rests,substantially as speci fled.

3. The chimney-holder, cone ordeflector,and perforated air distributer,substantially as specified, forming a base for sustaining the chimney inan upright position when removed from the burner.
